Abstract

The invention relates to a motor drive for an on-load tap changer with an electrical DC motor and a braking device for defined braking of this motor. According to the invention, the braking device has a first diode (D1), which, depending on the direction of rotation, is connected in series with or in opposition to the armature winding (AW) of the DC motor. In accordance with a further feature of the invention, the braking device has a second diode (D2), which is connected permanently in parallel with the shunt winding (NW) of the DC motor.

Description

For the motor-driven system of shunting switch
Technical field
The present invention relates to a kind of motor-driven system for shunting switch.Such motor-driven system is by applicant's the publication " Motorantrieb of company technische Daten TD292/01 " open.
Background technology
Such motor-driven system is for being adjusted to shunting switch the service position of each hope; In described motor-driven system, combine all machineries and the electric assembly needing for this drive system.The important mechanical component of such motor-driven system is load transport sector and controls transport sector.Described load transport sector direct manipulation shunting switch, its electro-motor for this reason with corresponding definite size is as CD-ROM drive motor.Control transport sector and comprise cam control gear, this cam control gear itself has the switching cam for handling the most different cam switches, and these switch cam is again the part of electric component.
The electro-motor of described motor-driven system is three-phase asynchronous electric motor in normal conditions; For different service condition also known direct current (DC) motor, described DC motor can use in different power stages.Known DC motor like this has armature winding, has in addition series connection winding and shunt winding.Having in the shunting switch of such DC motor, conventionally in motor circuit, there is brake apparatus, described brake apparatus is guaranteed accurately brake motor and stop described motor operation to exceed target location of target.Known such brake apparatus comprises a thyristor brake with electronic thyristor, and described thyristor is electrically connected like this, and the field of also preserving in the shunt winding of DC motor in the deboost phase is connected in contrast to the field existing.In addition, a kind of known thyristor brake is equipped with additional relay, and this relay is energized during the deboost phase.In order to start the deboost phase, by special contact, described thyristor is carried out to scratch start.Described thyristor brake is the only shunt winding effect to DC motor in principle.
In this known motor-driven system that comprises described brake apparatus, disadvantageously, described brake apparatus is on the one hand--as mentioned above--only to the effect of shunt winding and no longer completely normal work from about 50 to 55 degrees Celsius on the other hand.
Summary of the invention
Thereby task of the present invention is, a kind of DC of comprising motor and the further motor-driven system of the brake apparatus of exploitation are provided, this motor-driven system allows the high reliability in large-temperature range.
This task by have claim feature motor-driven system solve.
Special advantage of the present invention is, by novel diode arrangement replace brake apparatus according to the known thyristor of prior art.Said diode is connected in motor circuit like this, make the deboost phase along with opening of contact of motor protection and start, and according to brake apparatus of the present invention not only to series connection winding but also equally to the effect of shunt winding.At this particularly advantageously, change the direction of the respective diode to the effect of series connection winding by special braking protection contact.
Brief description of the drawings
The present invention should follow and exemplarily explain in more detail by accompanying drawing.This illustrate:
Fig. 1 when along the first traffic direction MR-operated motor drive system according to the circuit of brake apparatus of the present invention;
The circuit of Fig. 2 in the deboost phase along described traffic direction MR-;
The circuit of Fig. 3 when along the second traffic direction MR+ operated motor drive system;
The circuit of Fig. 4 in the deboost phase along described traffic direction MR+.
Embodiment
First should explain the circuit state in the situation of traffic direction MR-, as shown in Figure 1.Voltage path this overstriking from+number to-number illustrate.Carry out the pulse transmission for the set direction of the first diode V1 along this traffic direction by the contact of closed brake protector K3; K3 is energized.In addition motor protector K1 is energized, and armature winding AW and series connection winding RW are connected in series.Winding NW is switched on along separate routes.
Fig. 2 illustrates the deboost phase along this traffic direction.The set direction of the first diode V1 keeps by the closing contact of (excitation) brake protector K3, motor protector K1 de-energisation.Armature winding AW, series connection winding RW and the along separate routes arrangement of winding NW remain unchanged.Voltage path again overstriking illustrates.
Fig. 3 is illustrated in the circuit in the situation that traffic direction is contrary.In the time that pulse sends, carry out the set direction of diode V1 by disconnecting the contact of brake protector K3; K3 de-energisation.Motor protector K2 is energized, armature winding AW and series connection contrary connection of winding RW, and winding NW connects unchangeably along separate routes.Form the voltage path of this overstriking.
Fig. 4 is finally illustrated in the circuit of the deboost phase of the traffic direction MR+ explaining in Fig. 3.The set direction of diode V1 keeps by the break contact of (currentless) brake protector K3.Motor protector K2 de-energisation, armature winding AW, series connection winding RW and the along separate routes arrangement of winding NW remain unchanged.Produce shown voltage path at this, again from+to-illustrate.
In a word; be achieved as follows functional according to brake apparatus of the present invention: in the deboost phase; after disconnecting motor protection contact K1/K2, the field of also preserving of series connection winding RW in series or with armature winding AW is connected with armature winding AW according to direction of rotation with contact K3 on the contrary by diode D1.Another diode A2 and shunt winding NW are connected in parallel, to reduce the field also existing of winding NW along separate routes in the deboost phase with limiting.The present invention can be whereby realizes the effective brake of AC motor by effective impact of the field field on series connection winding RW but also on shunt winding NW not only.
